GLUCOCORTICOID RECEPTOR AGONIST COMPRISING NOVEL 1,2,3,4-TETRAHYDROQUINOXALINE DERIVATIVE CONTAINING PHENYL GROUP HAVING SULFONIC ACID ESTER STRUCTURE INTRODUCED THEREIN AS SUBSTITUENT

The object aims to find a novel pharmacological activity of a novel 1,2,3,4-tetrahydroquinoxaline derivative which contains, as a substituent, a phenyl group having a sulfonic acid ester structure introduced therein. A compound represented by general formula (1) or a salt thereof is useful as a glucocorticoid receptor agonist, particularly as a therapeutic agent for diseases against which a glucocorticoid receptor agonist (e.g., a steroid) is believed to be effective, such as inflammatory bone/joint diseases, inflammatory ophthalmic diseases (inflammatory ophthalmic diseases in the anterior or posterior segment of an eye). R1 represents a group represented by general formula (2a), (3a), (4a) or (5a); R2 represents a lower alkyl group which may have a substituent, a lower cycloalkyl group which may have a substituent, or the like; R3 represents a lower alkyl group; R4, R5, R6 or R7 represent a halogen atom, a lower alkyl group which may have a substituent, a hydroxy group, a lower alkoxy group which may have a substituent, or the like; and m, n, p or q represents a number of 0, 1 or 2.

Combined directed remote metalation-transition metal catalyzed cross coupling strategies: The total synthesis of the aglycones of the gilvocarcins V, M, and E and arnottin I

(Chemical Equation Presented) A key directed remote metalation (DreM)-carbamoyl migration strategy was applied in an efficient synthesis of the naturally occurring 6H-naphtho[1,2-b]benzopyran-6-one defucogilvocarcin V (1a, Scheme 11). The required biarylcarbamate 33d was best prepared by a high yielding Suzuki coupling reaction of 31a with the differentially protected trioxygenated naphthalene coupling partner 32d which was synthesized using a selective acylation of a juglone derivative. In the late stages of the synthesis, the triflate 39 served as the common intermediate to install the required C-8 vinyl group of 1a (Stille coupling) as well as the required substituents for the preparation of defucogilvocarcins M (1b) and E (1c). A variety of protecting group strategies were investigated and provided insight into which groups are preferred for the DreM-carbamoyl migration process. The strategic lessons learned from this total synthesis were applied in the successful total synthesis of the structurally similar natural product arnottin I (2).
